SPiN-NING-FRAME.

ject of the King of Great Britain, and reslf dent of the city of Valleyfield, in the Prov. ince of Quebec and Dominion ofCanada, have invented certain new and useful'lmthe following is a full, clear, and exactdescription.

This invention relates to improvements in spinning machinery, and the object of "the invention is to provide apparatus which will i be simple and durable inconstruction and economical in'operation.

A further object is to provide apparatus by means of which a predetermined .speed ..-may be obtained and maintained exactly, so that all spindles of the machine Wlllturn at exactly the same speed at all times A still further. object is to provide spinning machine in which repairs may be made to parts of the machine without'rendering all the spindles thereof idle.

Another object is to provide improved means for stopping the movement of individual spindles.

At the present time, spinning machines or spinning frames conslst usually of a framework carrying the spindles. A pulley is provided having its face extending the full length of ,the frame, and the spindles are driven singly or in small groups by belts passing over this pulle or drum. To produce efficient and uni orm spinning, it is necessary for all spindles to rotate at the "same speed, and for this speed to be uniform at 3.11 times. With belt drives, this is a practical impossibility. The use of belts not only produces imperfect spinning, but is very expensive to maintain, owing to the constant, wear and slackening of the belts and the power lost in' overcoming friction caused by the necessary tightness of thebelts. The present machines are usually belt driven. from line shafting, and this is in itself expensive, both from the point of capital investment and renewals, and from the'large amount of power required to over come losses due to friction and spindle belt slippage. Attempts have been made to drive ordinary spinning frames by means of direct connected motors, but this is not considered advisable, as the retention of the driving drums netessltates the use of low speed 'x'motors. which are large andexpensive, and 1. do not eliminate the troublesome spindle spind es spiral gear driven from a high by, a single motor at the end or by two disconnected if itbecomes necessary-to re- Specification of- Letters Patent.

"belts and slippage of same. 1 According to the present invention, the 'beltin and drum are eliminated, and the speed shaft, to which small. and inexpensive high speed' motors are directly connected. The. shaft and spindle gears runin an oil bath on ball. bearings, so that friction is as,

far as possible eliminated, the size of the '65 machine reduced, the power lost due to belt slippage elim inated,and uniformity of spindlespeed insured. Improved means are provided for quickly and easily stopping in- .dividual spindles to repair broken threads. The device is preferably made in comparatively short sections, so that these sections maybe built up into a machine of any desired length. Each machine may be driven Y motors arranged one at each endof the shaft, 1 or by a single motor arranged in the middle of the'machine. The shaft is also made up in short sections, which may be readily 1 pair any breakage in that section of shaft or mechanism driven thereby. Withthis arrangement of motors and sectionalshaft, never more than half of a shaft need be rendered inoperative ata'tim'e. The use'of short'sections of shaft further limits the. amount of dismantling necessary to replace I parts, and therefore reduces the time consumed in such repairs.

In the drawings whlch illustrate the in vention': Figure 1 is a plan view of one section the device showing parts broken away. Fig; 2' is an enlarged elevation partly in sectlon. a" Fig. 3 is'a transverse section on the line 33, Fig. 2. Fig. 4.- .i' a transverse section on the line 44,Fig.f2.

Fi 5 is a fragmentary rear elevation showing the spindle release;

F'i 6 is a fragmentary sectional view showing the method of joining two sections of shaft. I a 7 Figs. 7 and 8 are diagrammatic views illustrating methods of applying motor drive to the machine.

Referring more particularly to the draw;

ings, 11 designates a trough having at the ends flanges 12, by means of which it may be connected to adjacent troughs. A shaft 13 passes longitudinally through the trough, the shaft being preferably formed in sections of approximately the same length as the trougl1,.so that there will be one shaft coupling in each trough. The shaft is j ournaled in ball bearings 14: mounted in carriers 15, Supported on brackets 16 extending are constructed in sections of approximately the same length as the sections of trough, and in joining up these sections, the joints of the upper rail are staggered with respect to the joints between 'the trough sections, so that the upper rail may be used to the lower rail preferably extends through out a section of the trou h. The bearing carriers 15 are provided wlth lugs 20 which bear on the lower rail and support the upper rail. These bolts perform the triple function of holding the sections ofthe top rail together, holding both rails in place 'side of the gear.

and holding the supports 15- in place. -Each section of the trough is provlded with a cover 22. At the ends of the sections and if desired'at a suitable number of intermediate points, internal flanges 23 are provided, which stiffen the trough and form oil checks, so that if the machine is not pro-p erly leveled, -oil in the troughs will not run all to one end. These flanges are of such height between the front and back of the trough that the shaft passes over and not through them.

'Spira'l gears 24: are mounted between the upper and lower bearing rails 17 and 18 in .the ball bearings 19. These gears each. have a slightly tapered bore 25 for the reception of the tapered end of a spindle 26, the taper being so slight that the spindles will wedge in sufiiciently tight for driving purposes of their own weight or may be pressed in to a driving connection, but not so tight that they cannot be easily removed. Spiral gears 27 are mounted-on the shaft 13 to mesh with the gears 24. These gears 27 are each mounted on the shaft by means of a split tapered bush 28 threaded at the small end to receive a nut 29, which bears against the By tightening the nut against the side of the gear, the tapered bush is drawn through the gear and contracted around the shaft, so as to clamp the gear tightly to the shaft,

--both end portions for an equal assist in alining trough sections. Each section of- The coupling of the shaft sections is made by means of a special tapered bush 28- similar to the bushes 28 but having at its large end a reduced portion 30 taper-threaded to receive a nut 31. The bush 28, instead of having a cylindrical bore. similarly to the bush 28, has a polygonal bore to receive the polygonal end portions 32 of the shaft sections. The polygonal end portion of one shaft is twice as long as the polygonal end portion of the other shaft, and is slightly longer than the bush itself. Thus, the bush may he slid on to the longer polygonal end portion of one shaft, so as to other shaft, but when the bush is slid onto the other polygonal end portion, it engages distance as clearly shown in Fig. 6, and maybe held in this position by a split pin 33 if the bush is not properly tightened on the shafts by its nuts 29 and 31.

A short distance above the troughs 11, a brake rail 34- is provided, through which the spindles pass freely. This brake rail is supported at suitable intervals by brackets 35 secured to the fronts of the trough sections. Above the brake rail, the usual ring rail 36 is mounted on the poker rods 37 and carries a spinning ring 38 for each spindle.

Each spindle is provided in the space be tween the top of the trough andthe brake rail with a pair of spaced collars 39 between which the spindle is embrac'ed by the jaws 40 of a bell crank lever 41 mounted in a suitable bracket 42 attached to the'front of 1 6 the trough. A spring 43 is arranged to disengage the hold the-lever in such position that when the spindle is cperatively engaged in the gear 2a, the jaws will be out of engagement with both collars, so that there will be absolutely no friction'between the jaws and the collars. The necessity for this can be A readily understood when it is remembered 'that the spindle turns at approximately 10,000 revolutions per minute. may also be used to press the spindle into driving engagement with the pinion.

The assembly of the device is as follows As many trough sections as required are secured together by means of their endfianges 12. The alinement is facilitated by the fact that the-joints of the upper bearing. rails are staggered with relation to the joints between the trough sections. The shaft and gears 27 are set in place and a small high speed motor 44,may be connected to one or both ends of the shaft or a single motor, designated, 44 may be connected at an intermediate point. In the first arrangement, which is shown diagrammatically in Fig. 7, each of the -motors will deliver half the power required to operate the shaft, whereas with the arrangement shown in Fig. 8, the single intermediately disposed motor will This lever deliver the full amount of necessary power,

will not be necessary to stop more than the shaft in order to repair it, When 1t desired to effect repairs the couplingS of the shaft are loosened and the couplings slid along so as to disconnect the shaft from the adjacent shafts, the pins 33,,being of course removed. The affected shaft, with its attendant mechanism, may now be removed g shown in Fig. 7 the entire machine with the excep tion of the 'shaft'remo'ved may remain in v r operation, as the With the motor arrangement drive is from both ends, and with the arrangement shown in Fig. 8, one-half of the shaft and that part of, the other half not cut off from the motor by'the ,remo'val of a shaft s t on will remain in The operation of {the ldevice as follows :-The shaft 13 is "rotated by its driving motor and rotates the-spiral gears, 9.7 which mesh with the spiral gears 24 and p 25 firi. ethe same at high speed. The tapered spind les lit in the tapered bores of the gears "24safliciently tight so that the spindles rotate with the gears, without any slip or loss 1 9*. power. The jaws of the levers 41 remain 8x3 out of contact with the spindles so that there [is no friction, and thesprings 43 holdthese' levers against swinging with vibration of'the. machine and striking the spindle collars,-

which would result in a chattering .sound and rapid wear. When it flS desired tore 'move a bobbin from any spindle or to stop .the bobbin for the purpose of joining a broken thread, the operator presses the lower end' of the lever 41, thus raising the-jaws 40,into contact with the upper collar 39,

' and lifting the spindle up in the gear. This slight upward movement breaks the driving engagement, and at the same time jams the upper collar against the brake rail,'-so that the spindle is almost instantly checked. When it is desired to restart the spindle, all, that is'nec/essary is to release the lever proper position by its spring 13, the spindle dropping at the same time into driving engagement with the gear. When thedev-lce is in operation, the troughs-are closed by their covers .22, and are eachch'arge'd with such a depth of oil that the lowest part of the run in theoil and the gears and bearings throughout will be lubricated on the splash system. If the machine is set up out of level, the internal flanges 23 will prevent the oil'accumulating at one end and leaving the other. end dry.

As shown in the drawings, the gears is approximately 2.6 to 1, and thus a motorwith a speed of 3800 to 4000 revolutions .per mmutewoulddrive the spindles as at 9880 to 10,400 it. P. M.

The upper bearing of the pinions must be slightly spaced from the cover, as shown, so that any'oil which works up on the spindles will be thrown ofi under the cover. If the cover touches the bearing the oil would 'travelthrough the cover andbe thrown ofi outside. In order to prevent o1l creeping through the joint between the trough and cover the latter must be set into the trough as shown. It will be understood that the single line of shaft shown and described is duplicated in each frame, the shafts being arranged parallel. From this it Wlll be apparent that for repairs only part of one side of a frame need be stopped and of the pinions to pre-' that in dofling only one side of a frame need. i

be stopped at a time, thus getting the maximum production per frame.
